Rodents and wildlife are a major source of infection. Clinical signs in cattle include fever, heamoglubinuria, jaundice, abortion, mastitis, reduced in milk production, reproductive failure and death. In this survey, the seroprevalence of Leptospiral infection in dairy herds and the relationship between seroprevalence and animal and environmental factors in Tabriz were investigated. 229 serum samples randomly collected from herds since December 2002 to November 2003. Sera were tested by MAT using live Leptospira interrogans serovars: Hardjo, pomona, icterohaemorrhagiae, grippotyphosa, canicola and ballum. Twenty four percent of sera were seropositive against one or more of studied serovars. Pomona and grippotyphosa were detected as the most-prevalent serovars with 34.2% and 32.9% respectively. All of sera were seronegative for hardjo. The Chi-square method used for seasonal tend of seroconvertion agains...

Admittance measurements are used to extract deep level parameters in order to correct the dependence of capacitance voltage measurements on the frequency of the AC signal applied for irradiated silicon detectors.

Scanning Electron Microscope (SEM) and X-ray Diffraction (XRD) have been used to study the templates influence on the morphology of the produced samples. Although the phase structure remained as a tetrahedron amorphous cristobalite-sin-SiO2 (101,100), rhombohedron and cubic NiO, but samples with different morphology (homogeneous nano spherical, nano rose flower and nano cubic shapes) have been achieved. These fine nanoparticles as syngas catalysts in Partial Oxidation of Methane to Hydrogen and Carbon Monoxide (POM) have been studied. Because of high Hydrogen production, it is a candidate to be a green fuel. A fixed-bed reactor at P = 1 atm, T = 800 degrees C, H2/CO = 1.8, GHSV (CH4) = 6000/hr and BET = 25, 63.5 and 87.1 m2/gr have been used as POM catalyst. From other hand these fine compounds could be converted to metallic nanotube (nanofiber) at above 850 degrees C and also bamboo shape tip mode carbon nanotube by thermal chemical vapor deposition at 800 degrees C. Transmission Electron Microscopy confirmed the metallic nanotube or single nano crystal growth. The Raman spectroscopy of all samples has been studied to confirm the different formation of Ni-Si. Choosing different templates for production of these nanoparticles could create width range of medical and industrial applications.
